Hi I have a hb2400vd2m20 air handler and need to know what wires are needed to hook up to my thermostat its a Honeywell, as of the moment there is no heat pump it just the air handler running. I know there...


Honeywell 5000, 8000, 8000 iaq, prestige, round dial analog, digital Honeywell redlink. 1 heat 1 cool thermostat 3 heat 2 cool thermostat. does the stat u have do conventional a/c and heat pump. red wire is hot wire 24 volts not heating its your 24 volt control power. this will be r on your board and t-stat and red wire. y is for cooling mode and is yellow and will be noted y on both board and t stat. green is fan on the indoor furnace and will be g on board and t-stat and the wire is green. blue is the common side of the transformer labeled b on both board and t-stat. I did not see brown on your schematic I looked up I seen orange which is your reversing valve wire for the heat pump whether its calling for cooling or heat this is what changes the flow of Freon to make it to the indoor coil as warm Freon or cold when called for in heat or cool. the thermostat if a vision pro 8000 needs to be programmed in the installer mode which if this is the t-stat u have u need to read through the heat pump section. the green hooked to the orange doesn't look right on the print but that's the breakdown. http://www.manualslib.com/manual/277678/Haier-Hb2400vd2m20.html?page=11#manual heres your schematic

HE heat pump won't talk with old air handler?


The fact is, the air handler supplies the voltage, blower, and electric heat. In order for the heat pump to work correctly, the wiring from the thermostat and heat pump need to be hooked up right to the air handler. The thermostat is what tells which component to come on. If the fan stops, but the condenser keeps going, you either have a faulty fan relay on the air handler, faulty thermostat or wiring, faulty wiring at the heat pump, or the contacts on the new unit are sticking, which is highly doubtful considering it is working now. I hope I have helped you understand this a little more. Good luck and don't let them push you around, get someone that knows what they are looking at.

WIRING THE THERMOSTAT TO AC UNIT THEN FROM THE UNIT TO HANDLER


Generally, you would go from the thermostat to the air handler, and then, from the air handler to the outdoor unit. I don't know if you have a heat pump or not, so I will give you a simple diagram and you can contact me if you need more.

Thermostat : Y G R W and sometimes C
Air handler: Y G R W and C
Outdoor unit: two wires connecting to the contactor ( not heat pump)

Thermostat; Y--------------Y(air handler cooling)------------------one side of contactor, outdoor unit
G-------------G (air handler, fan)
R--------------R (air handler ,hot)
W-------------W (air handler, heat)
C--------------C (air handler, common)------------other side of contactor, outdoor unit

This is a typical wiring diagram. Just contact me if you have something different. Hope this helps. Stay cool. mark

Originally installed in 1978 as a heat pump. Threw away the outside unit. Want to use the electric inside furnace/air handler as a shop heating source. I don't know how to wire in the thermostat which...


Red is 24v from transformer to terminal R
Green is to Terminal G for the air handler fan motor
Yellow is to Terminal Y for calling cooling to the compressor and fan outdoor unit
White is to Terminal W for calling the heat trips which are usually sequenced to keep them from all coming on at once and over drawing Amps and kick off breakers.
Orange was for outdoor reversing valve for a heatpump system
Blue or Black is usually used for common or negative continuity in the circuit such as Red wire and Blue/Black wire to power a thermostat features on digital T-stats. If not digital T-stat then no common is needed to hook-up at T-stat

My air handler fan will not come on during heating but will operate during cooling - Anerican Standard unit TWEO65E13FBO


Hi,
Please check the thermostta first. Take the thermostat to the air handler and hook up on a short thermostat leash. The unit should work properly, then its for sure that the problem is going to be in your thermostat wiring. If problem persists then we are troubleshooting a thermostat.

Let us know if you need further assistance.
Thanks for contacting Fixya.com

Temp in my home will not drop below 81 degrees


Air Handlers differ in the way they adjust there variable speeds. Carrier you just plug into a pin. Trane has dip switches with directions on the fan housing. Before you try to adjust please kill power to air handler. Varriable speed are very sensative to voltage. If I new your air handler brand I could help. But just check the wiring diagram and they may ahve dirrections on there for setting speed. Need more help call back Rus
